The swinging leaf B of the hinge has at an intermediate point of its length a single pintle-lug 6 which is arranged to slide vertically on the pintle and carries a radially projecting cam-lug 6 which latter coacts with an arcuate helicoidal cam-surface a formed upon a special cam-lug a concentrio with the pintle C and projecting from an intermediate point of the fixed leaf A in such manner as to project under and to support the lug b of the swinging leaf B. The special form and slope of the different parts of the helicoidal cam-surface 0: may

be as described and shown in i y copendhereinafter seen.

Surrounding the pintle C is a coiled j spring E which has its respective ends bent at right angles parallel to its axis as shown at e and 6 directly upon the pintleC nor does it touch the latter, but the pintle-lugs a and b are The spring is not supported provided with cylindrical bosses a and b (the latter preferably somewhat tapered as shown) which cooperate with and receive the ends of the spring, being of such diameter as to pass inside said ends. When properly assembled the spring E is secured in place upon the cylindrical boss a, which latter is provided with an annular groove a at its base, and the end coil 6 of the spring C is made slightly smaller in diameter so that it snaps into the groove a and holds the spring permanently in place on the lug (4 To keep it from rotating there are formed on the side of the lug (t a pair of raised snugs a and (4 which are placed and formed so that the upwardly bent end 6 of the spring snaps between them and is likewise resilientlyv held against coming out. .It is to be observed that at its lower end the spring does not rest upon the flat shoul der 5 of the lug b at the base of the boss 5 in the closed position of the hinge, but only after the hinge has been opened to a greater or less extent depending upon the point at which it is desired that the spring come into action. The downwardly bent end a of the spring is so disposed as to lie in the path of the cam-lug Z2 in opening as shown; and also is so placed that it does not strike upon the advance face D of said cam-lug until after the door has opened to a certain angle, preferably the same angle as corresponds to the striking of the end-coil e of the spring against the shoulder 5 The positioncorresponding to this angle of opening at which the spring first comes into action is illustrated in Figs. 5 and 6. It will be observed therefore, that the action of the spring does not begin until after the door has opened through a certain an le and at that point the spring starts suddenly into action, and moreover, this action is of a double nature namely, axial compression, and also an axial torsion of the spring. The torsion acts directly to close the door, while the compression acts to assist gravity by pressing lug upon the cam-surface a From a small opening of the door this ac tion is slight so that the door will not be voilently slammed under ordinary circumstances, but at the same time the action of the spring is sufficient to overcome any wind-pressure directlyv against the face of the door when wide open.

An important result accomplished by having the spring secured practically fast to the fixed hinge-leaf (although readily removable therefrom by a slight twisting movement) is that the spring can not get lost when the door is taken ofi its hinges as in winter by removing the intle. If the spring were free in. place wiien the 'pintle is lifted out, the spring would fall and roll away, or if kept it would very likely get lost as being a seperate object; but according to my constructionthis is impossible as the spring remains firmly attached to the upper pintle-lug at all times. If desirable the same fixed leaf and spring can be used interchangeably with two or more swingim leaves fixed to different doors, as for exam ple, where a screen door in summer is replaced by a storm door in winter, the same spring serving for both.

Having thus described my invention. what I claim as new and desire to secure bv Letters Patent, is: u

In a gravity-hinge the combination Wltil a pair of hinge-leaves having interacting cani-lugs which coact to cause a closingmovement of the door by gravity, a spring acting between the two hingedeaves which is distorted by the opening thereof beyond a certain minimum angle of opening of said leaves; the ends of said spring engaging ing hinge-leaf both having pintle-lugs a pintle passing through said lugs and pivotally connecting said leaves, interacting cams upon the respective lugs whereby the swinging leaf is raised with respect to the fixed leaf in opening the door, a coiled spring surrounding said pintle and fixed to one of said leaves concentrically with said pintle but out of contact therewith, and an annular boss or nipple on the other hingelea't adapted to extend within the coil of said spring and hold it in said concentric position; there being at the base of said boss or nipple a transverse shoulder against which the spring is adapted to seat; said spring having a normal length shorter than the distance between the opposing faces of said pintle-lugs; whereby said annular boss or nipple advances into the free end of said soring upon the opening movement of tire )()l' and maintains it in said concentric position and guides it to a seat upon said shoulder.

' 10. In a hinge, a pintle having an en- 1 A iaiged aead, said heao haw mg a llat side, in combination with a pintle-lug in which said pintle is adapted to be mounted, a raised overhanging snug formed on one side of said pintle-lug. said snug projecting over the upper face of said head \vnereby to prevent said pintle from rising. out of said lug except when it is turned into position where said flat side registers with said snug and a ren ble key or like member mounted on said i intle-lug in position to abut against the fiat side of said pintle, whereby the lat ter is prevented from turning.

11. In a gravity-hinge in combination with pair of hinge-leaves having interacting cam-lugs which coact to cause a closing movement of the door by gravity, a spring which interacts between said hinge-leaves and is caused to be compressed by the opening movement thereof, said spring acting by compression through said cam-lugs to assist the action of gravity in closing the door; and said spring further having its ends so connected with said hinge-leaves to be twisted thereby beyond a certain mi imum angle of opening of the leaves, whereby said spring further acts directly by torsion to turn the leaves into closed position at any angle beyond said minimum angle.

In witness whereof, I have hereunto set my hand this seventh day of March, 1907. RUDOLPH Gr. WVINTER. In presence oi- GEORGE W. CoLLns, Ensin M. HoTz.
